Structure–Performance Interplay and Mechanical Degradation Modes in Lithium Cobalt Oxide Cathodes: Implications for Flexible Lithium-Ion Battery Design ↗
Lithium cobalt oxide (LCO) remains the industry-standard cathode for lithium-ion batteries in consumer electronics, but its mechanical reliability under repeated deformation—a critical requirement for flexible and wearable devices—has not been systematically investigated. Here, as-manufactured LCO electrodes are subjected to repeated bending (up to 3000 cycles) at diameters of 100, 50, and 25 mm, followed by post-bending electrochemical, microstructure, and electrical characterization. Bending-induced degradation mechanisms are found to be strongly impacted by the LCO particle size. Coarse-par…

State of charge estimation for lithium-ion battery balancing systems considering branch current dynamics under non-ideal switching ↗
State-of-charge (SoC) estimation is essential for lithium-ion battery management systems. In practical battery packs, balancing circuits are commonly used to reduce cell inconsistency. However, most existing balancing-aware methods treat the balancing branch as an ideal binary switch and directly determine the balancing current from the switching command. This simplification neglects branch-current dynamics under non-ideal switching, which may introduce mismatch in cell-current reconstruction and reduce estimation accuracy. To address this issue, this paper proposes an SoC estimation method fo…

A feature selection and model fusion framework for lithium-ion battery state of health estimation under capacity regeneration phenomena ↗
Data-driven models have been widely employed for the state of health (SOH) estimation of lithium-ion battery in recent years. However, during long-term aging, batteries are prone to exhibiting significant capacity regeneration amidst the normal capacity fading. Traditional data-driven methods cannot efficiently extract features that reflect the localized behavior, and the single estimation model also fails to capture complex aging behaviors, leading to a decline in SOH estimation accuracy. To address the issues, this paper proposed an SOH estimation framework that combines a feature selection…

Oriented composite phase change material with high thermal conductivity at low filler loading for battery thermal management ↗
Conventional phase change materials (PCMs) use thermally conductive fillers to improve thermal conductivity and mitigate battery temperature rise. However, excessive filler addition inevitably weakens energy storage components and reduces the latent heat of phase change, making it challenging to balance thermal conductivity and latent heat. In this study, hexagonal boron nitride (h-BN) and spherical aluminum oxide (Al 2 O 3 ) were used as thermally conductive fillers, and paraffin (PA) served as the phase change matrix. An oriented composite phase change material (OCPCM) possessing both high t…

Fe2O3–CdS@MWCNT ternary nanocomposite: a dual-function electrode for energy storage and electrocatalytic oxygen evolution ↗
Engineering electrode materials with energy-storage functionality and catalytic water-oxidation sites within a unified architecture is a practical challenge in electrochemical research. Herein, we disclose a three-component nanocomposite (Fe 2 O 3 –CdS@MWCNT). α-Fe 2 O 3 nanoparticles and CdS crystallites are anchored within the MWCNT framework. Phase formation was investigated by X-ray diffraction, which revealed reflections consistent with the rhombohedral hematite and hexagonal wurtzite lattices. The surface area of the composite was 99.45 m 2 /g according to Brunauer–Emmett–Teller measurem…

High-Temperature Solid-Particle Thermal Energy Storage Integrated with Coal-Fired Power Plants: Current Status and Future Trends ↗
The increasing penetration of renewable energy requires coal-fired power plants to operate with greater flexibility, while deep load reduction and frequent load variations challenge combustion stability, efficiency, and equipment reliability. High-temperature solid-particle thermal energy storage (TES) offers a promising approach to decouple boiler heat supply from turbine power demand. This review compares particle heating, discharging, transport, and system-integration strategies and relates reported findings to key design and operational constraints. Solid-particle storage media can operate…

Embedded artificial intelligence in battery management systems: Pruning and quantization for efficient state-of-charge and state-of-health estimation ↗
Online battery management requires accurate state-of-charge (SOC) and state-of-health (SOH) estimates within strict memory and timing budgets. To address these constraints, this work investigates how stateful long short-term memory (LSTM) networks with multi-layer perceptron (MLP) heads can be optimized for embedded artificial intelligence (AI), using structured pruning and recurrent-weight quantization to reduce memory and computational costs while retaining estimation accuracy on an STM32H753ZI microcontroller. Using the open Lithium Iron Phosphate (LFP) Cycle Ageing Dataset , full-precision…

Thermal performance enhancement of lithium-ion battery modules through coolant selection and cold plate structural optimisation ↗
Effective thermal management is critical to ensuring the safety, performance, and lifetime of lithium-ion battery modules used in electric vehicles. This study investigates two complementary strategies for enhancing indirect liquid-cooled battery thermal management systems: the use of environmentally benign coolants and the optimisation of practical cold-plate geometries. First, propylene glycol–water (PG–W) mixtures are evaluated as non-toxic alternatives to conventional ethylene glycol–water (EG–W) coolants using a validated three-dimensional computational fluid dynamics (CFD) framework inco…

Multiple model predictive control strategy for improved energy efficiency of a data-driven commercial cold storage system ↗
Commercial cold storage systems are energy-intensive thermal processes where fluctuating ambient temperatures often drive internal heat gains, leading to compressor short-cycling and reduced efficiency. To address these challenges, this study develops a Multiple Model Predictive Control (MMPC) strategy based on a data-driven state-space architecture. Utilizing a modified high-fidelity benchmark model from Aalborg University, subspace system identification was employed to characterize the system dynamics across a 14-day tropical temperature profile (8.9 to 32.8°C). The model incorporates ambien…

Decoupled DC-bus voltage regulation and adaptive energy management for fuel cell/battery/supercapacitor powered vehicle ↗
This paper presents a hierarchical energy management and control framework for a fuel cell–battery–supercapacitor hybrid electric vehicle with regulated DC-bus voltage. The proposed architecture decouples DC-bus voltage regulation from energy management by generating a net load current enabling flexible and constraint-aware power allocation among the energy sources. An adaptive frequency-based energy management strategy is developed, incorporating state-of-charge-dependent cutoff frequency and explicit battery availability logic to ensure safe operation under boundary conditions. Inner current…

How to assess evidence about Battery Storage
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
